I wonder why Microsoft doesn't make Edge a privacy-oriented browser. I'm surprised they think they can make more from the data economy than they would gain by seriously hurting Google et al.

There's too much money to be made foisting payday loans on the dwindling userbase. https://www.howtogeek.com/769427/microsoft-edge-wants-to-giv...

Why weren't separate cookie jars the default in the first place? I know that browsers other than Firefox have no real incentive to protect your privacy, but I'm wondering why cookies were designed to be shared among different pages in general

There are legit cross-domain use cases. A good example is how someone here mentioned (comment seems deleted though) account sessions being shared between Atlassian products like JIRA and BitBucket.

The problem with that is domains are a poor way of representing ownership that can be trusted. If the web was rebuilt from scratch, a better approach might be to allow cookies to be shared between secure sites using the same certificate. But that adds more complexity that I'm not sure is worthwhile. The web can absolutely get away with not having shared cookies.

While I'm not a friend of tracking via cookies nor tracking in general there is some utility there. For example SSO may be done over cookies, like oauth iirc. I don't know of many other use cases though that couldn't be contained with header etc.

RFC2109, from 1997, had this:

8.3 Unexpected Cookie Sharing

A user agent should make every attempt to prevent the sharing of session information between hosts that are in different domains. Embedded or inlined objects may cause particularly severe privacy problems if they can be used to share cookies between disparate hosts. For example, a malicious server could embed cookie information for host a.com in a URI for a CGI on host b.com. User agent implementors are strongly encouraged to prevent this sort of exchange whenever possible.

Earlier quoted context omitted.

This seems to be a middle-ground. You can more confidently allow third-party cookies, which means that certain features that broke with the blocking of all third-party cookies will now be able to work, but you maintain most of the protections that you gained when you used to block them.

So.. Standard? or Off? Ever since this has been announced, I understand how it works, but the browser does not communicate at all which setting level it maps to, or if I even need ETP on at all and it's just always on.

ETP Strict

Before anyone jumps to why Chrome doesn't block third-party cookies, some context:

Regulators did warn Google NOT TO block third-party cookies before they provide a replacement, UK CMA accepted the latest proposal from Google: https://www.gov.uk/government/news/cma-to-keep-close-eye-on-...

Apple's tracking rules also raised a lot of anti-trust concerns, giving advertisement in App Store unfair advantages among other ad platforms. Latest from German Government: https://www.bundeskartellamt.de/SharedDocs/Publikation/EN/Pr...

Banning third-party cookies will increase the gap between Google, Microsoft, Apple and other ad platforms, because they can still track you based on your account (e.g. Gmail, Hotmail, iCloud). It's a huge red flag for antitrust cases they are facing (especially Google).

It appears that cookie isolation is always on.

If you want to further mitigate risk, you adjust your settings block all third-party cookies.

Reminds me of what Google Chrome (and others browsers) did for cache. That's clever, not 100% sure this will prevent tracking, but at least it makes tracker's life a bit harder.

Quoted post unavailable.

To some extent chrome only cares about google being able to invade your privacy, if google can get information a different way anyway then its a good thing to block it for everyone else
